Growth Stages

1

Germination & Seedling

7-14 days

Seed germinates in warm soil (60-70°F); cotyledons emerge within 7-10 days. Young seedlings develop first true leaves.

Ensure consistent soil moisture; maintain warm soil temperature. Thin seedlings if directly sown; provide light as soon as sprouts emerge.

2

Vegetative Growth

2-3 weeks

Bush plant develops sturdy stems, compound leaves, and a compact growth habit. Plant reaches 12-18 inches tall without significant flowering.

Keep soil consistently moist but not waterlogged. Provide full sun and good air circulation. Mulch to retain moisture and regulate soil temperature.

3

Flowering

1-2 weeks

Plant produces small white or pale yellow flowers at leaf axils. Flowers are self-fertile and develop into young green pods.

Maintain steady watering; flowering stage is critical for pod set. Avoid excessive nitrogen which reduces flowering. Watch for pests.

4

Pod Development & Harvest Maturity

2-3 weeks

Thin green pods develop rapidly from fertilized flowers, reaching 4-5 inches long with pencil-thin diameter. Pods are tender and snap cleanly when bent.

Continue consistent watering. Harvest regularly to encourage continued pod production. Pick pods when young and tender for best flavor.

5

Extended Harvest & Senescence

3-4 weeks

Plant continues producing new flowers and pods if harvested regularly. Without harvest, pods mature, seeds enlarge, and plant slows production.

Daily or every-other-day harvesting extends production by 2-3 weeks. Stop harvesting when plant shows decline to allow natural seed maturation if desired.

Common Pests

  • Hand-pick beetles and egg clusters; use spinosad or neem oil; plant trap crops; encourage beneficial insects like parasitic wasps

  • Spray with strong water stream; use insecticidal soap; introduce ladybugs or lacewings; neem oil for severe infestations

  • Increase humidity; spray with water; use miticides if severe; neem oil or sulfur dust effective

  • Yellow sticky traps; spray undersides of leaves with insecticidal soap; neem oil; encourage parasitic wasps

  • Row covers until flowering; hand-pick beetles; insecticidal soap; diatomaceous earth

  • Improve air circulation; avoid wetting foliage; sulfur dust; neem oil; resistant cultivars

  • Remove infected leaves; improve drainage; avoid overhead watering; fungicidal copper spray; remove plant debris

Uses

🍳

Fresh Steamed or Sautéed Beans

Culinary

Triomphe de Farcy's slender pods are ideal for gentle cooking methods like steaming, sautéing with garlic and olive oil, or adding to salads. The delicate pods remain tender and sweet when cooked briefly, making them a refined addition to gourmet cooking. [source]

🍳

French Fine Beans (Haricots Verts)

Culinary

This variety is the classic French haricot vert, traditionally prepared à la française—trimmed, blanched, and served with butter and seasonings. It's celebrated in French cuisine for its tender texture and delicate flavor. [source]

🍳

Raw Pod Snacking

Culinary

Young, tender pods can be eaten raw as a nutritious, crisp snack or added to fresh vegetable platters. The pencil-thin pods are particularly sweet and tender when picked at peak ripeness. [source]

🏠

Seed Saving & Succession Planting

Household

Allow some plants to mature fully to save seeds for next season; beans self-pollinate making them ideal for home seed saving. Multiple plantings 2-3 weeks apart extend harvest throughout the season. [source]

🦋

Nitrogen Fixation & Soil Building

Wildlife

Like all legumes, Triomphe de Farcy hosts nitrogen-fixing bacteria in root nodules, naturally enriching soil. Incorporating spent plants into compost or tilling them under builds soil fertility for subsequent crops. [source]

Harvest Tips

Begin harvesting 50-60 days after planting when pods are 4-5 inches long and pencil-thin, still tender and bright green. Harvest every 2-3 days for peak tenderness; pods toughen and seeds enlarge if left too long. Snap pods off gently from the vine, or cut with scissors to avoid damaging the plant. Morning harvesting yields the crispest, most tender beans. Regular harvesting encourages continuous production throughout the season.
